[Rd] test for readline installation fails if installation location non-standard (PR#8104)

[David Kreil]

Dear Peter,

Fair enough. For many people who install R without root rights, however, this 
is a first stumbling block so perhaps it might be worthwhile adding it to an 
"Installation how-to" document.

I found another hicup:

ld: Unsatisfied symbol "finite" in file colors.o

Fix: replace "finite" with R_FINITE in colors.c line 269.

Do you want this separately submitted via Jitterbug?

With best regards,

David.
